SHEET-JOGGING DEVICE FOR PRINTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 738,641, dated September 8, 1903.

Application filed April 30, 1903.

To (Mi/ whom, it may concern:

Be it known that I, JAMES W. P. TAYLOR, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Sheet-J oggin g Devices for Printing-Presses, of whichtthe following is a specification. My invention relates to devices employed in connection with the delivering mechanism of printing-presses for automatically jogging or evenly delivering the sheets of paper as they are successively delivered by the flier on the fly board or table;

The invention consists in the improved 'means for evenly delivering the paper hereinafter described, and illustrated in the accompanying drawings, in which-- Figure 1 is aperspective view of the flier and fly-board of a printing-press and my improved jogging device or devices for evening the sheets of paper combined therewith. Fig. 2 is an enlarged side elevation of one of the jogging devices. Fig. 3 is a rear view of the Fig. 4 is a central vertical section of the device shown in Figs. 2 and 3. Fig. 5 is a rear view of part of one of the jogging devices provided with a contact-piece diiferent in construction from that illustrated therewith in the other views. Fig. 6 is a perspective view of one of the adjustable stops or gages.

In the accompanying drawings, A designates the flier of a printingepress, and B the fiyeboard upon which the sheets are delivered from the flier. These parts may'be of any usual or approved construction and used in connection with anypreferred style of print- The flier is mounted upon the shaft 0 and has a number of sticks a, that are connected with the shaft 0 in any suitable way. The fly-board is provided upon its upper surfacewith a number of slightlyraised dovetail ribs 2 2, upon which are mounted the adjustable gages or stops 3,with

which the edges of the sheets of paper are made to engage as the latter are delivered upon the fly-board and which operate to hold V the sheets evenly laid one upon the other.

The gages or stops 3 have relatively broad feet or bearings at their lower ends in which are formed dovetail grooves 4, that fit the Serial No. 154,992. (No model.)

ribs 2. To hold the stopsin place, each of them is provided with a lever or clamping arm 5, that has a fulcrum or pivot about which it moves and which also serves as a connection between the lever and the body of the stop or gage. A convenient manner of mounting the lever or clamping arm 5 is that illustrated, wherein it is shown as being arranged between lugs or flanges 7, carried by the gage and to which it is pivoted, as indicated at 6. A set-screw 8 is employed to adjust the clamping-arm 5 and to force it into engagement with one edge of'the rib 2, as clearly indicated in Fig. 3 of the drawings, whereby the stop or gage is securely held in any position to which it may be adjusted.

By thus constructing the gage I am enabled to mount it entirely above the receiving-table or fly-board, which therefore does not have to be slotted or perforated for the gage or its attaching means and to firmly support it upon a rib of so slight elevation above the surface of the board that it will not interfere to any practical extent with the smooth and uniform laying of the sheets. The stops may be easily and quickly adjusted while the press is in motion, and being entirely above the upper surface of the delivery-board they are always in sight and easily accessible.

The paper-jogging devices are arranged to be operated directly by the flier and are also situated entirely above the delivery-board, being constructed so as to be mounted upon the ribs 2. The main frame 9 of each jogging device is provided at one side with a clamp consisting of a lever 5 and set-screw 8, similar to that already described in connection with and for holding the stop 3. In the frame or body 9 of the jogging device there is mounted a horizontally-movable bar 11, carrying at its rear end the jogging or pushing plate 10, that engages with the edges of the sheets as they are delivered from the flier and pushes them into place between the stops or gages 3. Abell-crank lever 12 is mounted upon a suitable shaft 13 in the frame of the jogging device and hasbne of its arms connected with the horizontally-movable bar 11, while its other arm is connected with a vertical movable slide 14:, that is mounted in suitable ways in the upper porthe slide 14 is provided with a contact-piece 16, arranged in the pathof one of the flysticks a, so that when the latter moves downward to deliver a sheet. it engages with such contact-piece and moves the slide let downward and the pusher or jogger plate inward at the instant the sheet is delivered upon the receiving or fly board. The moment the flier begins its return movement the spring or springs 15 restore the parts to their normal positionthat is, with the plate 10 moved outward and with the slide and contact-piece elevated-this movement operating to push the last-delivered sheet between the stops 3, directly above the previously-delivered sheet, where it is held by the jogger or pusher plate 10, this being normally held in engagement with the edges of the sheets by the springs 15.

The distance between the upper surface of the fly-board and the under surface of the flier-sticks differs in different machines and sometimes in the same machine, according to the nature of the flier and delivery-board being employed, and it is therefore desirable to be ableto make provision for having the jogging devices accurately operated no matter what the relation of the flier and fly-board may be. Accordingly I prefer to mount the contact-piece 16 upon a screw 17, which secures it to the slide 14. and to arrange between such slide and the contact-piece a spacing sleeve or piece 18. If theflier fingers or sticks are relatively high above the delivery-board, a long screw and spacingsleeve will be employed, whereas if they are closer together shorter parts will be used. It sometimes happens that it is desirable to arrange the delivery-board very close to the flier when in its lowermost position. In such case the jogging devices shown and described may be too high to have the flier-sticks en gage directly with the contact-piece 16. Under these circumstances the fly-sticks are adjusted so as to straddle the jogging devices,

' piece has laterally-extended depending arms arranged to be engaged by the .two' fliersticks a on either side of the jogger. Two or more jogging devices will usually be employed, according to the size of the sheet being delivered.

Among the advantages incident to my invention the following may be mentioned. It is entirely practicable to adjust the jogging device as well as the gages while the press is in operation- ,This is due in part to the fact that the gages and jogging devices are entirely above the delivery-board, which renders them both easily accessible and f nlly exposed to view. The operating mechanism of the joggingdevice is exceedingly simple, and by properly proportioning the length of the arms of the bell-crank lever to each other the requisite amount of movement can be imparted to the jogger or sheet-engaging plate or member whether the siidel t have a relatively long or short movement. Further, it will be observed that the sheetengaging plate 10 remains in contact with the sheets thathave been delivered throughout most of the time, being retracted only just before the sheet is delivered by the flier.

Having described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination with the delivery-board of a printing-press provided with guide-ribs, of the adjustable means for evening the sheets delivered to such table, arranged to slide upon the said ribs, and each provided with a pivoted clamping-arm arranged to engage with the said rib and hold such means in place, substantially as set forth.
